  • Publication number: 20180078646
    Abstract: Disclosed is a tigecycline composition for injection, comprising the active component, tigecycline, and a propping agent. Also included is a stabilization agent. Also disclosed is a stable, pharmaceutically acceptable reconstitution liquid having freeze-dried tigecycline. The tigecycline composition for injection of the present invention has good redissolution, and can dissolve without intense shaking, thereby avoiding foams caused by intense shaking. Upon testing, the tigecycline composition and the tigecycline composition-diluted reconstitution liquid prepared in the present invention prove to have substantially lowered oxidation degradation and epimer generation and increased stability of the tigecycline preparation.
